I am suspicious that the early 14s have a known problem and in typical GM fashion they find it cheaper to lose a few customers tather than fix the problem. Good luck with yours. I gave up fighting with them.

I couldn't agree more. I notice my pump is loud too. I believe there is an underlying issue that they will not resolve hoping the warranty will run out. Did you get rid of your truck or you just dealing with the issue ? I'm thinking heavily of trading mine.
